Vswitch and vro Interface

Vswitch and vro Interface

(I) Main vswitch Interfaces

(1) RJ-45 Interface

The switch has 8 RJ-45 Interfaces

(2) SFP Interface

The SFP interface is the interface of a switch. The SFP module must be connected to an optical fiber or twisted pair wire. The SFP module has multiple types and needs to be selected based on the transmission distance. The optical fiber is connected to the SFP module through the SC connector or the ST connector. Multiple types of optical fibers are available, depending on the transmission distance and SFP module type.

(3) SC Optical Fiber Interface

The optical fiber connects to the SC optical fiber interface through the SC connector, saving the SFP module for connecting to the switch.

(4) Combo Port

For example, S2700-9TP-EI (DC) has a 1 Gigabit Combo port, Combo port contains a RJ-45 interface and an SFP interface, can only use one.

⑸ Console interface

(Ii) main router interfaces

Compared with firewalls and vswitches, vrouters have many types of interfaces, RJ-45 twisted pair interfaces, and also have interfaces connected to various Wan.

LAN interfaces are the same as vswitches, omitted)

WAN Interface

(1) synchronous SERIAL port serial) such as serial 1 and SERIAL 2,

Usage DDN, Frame Relay), X.25, and PSTN analog telephone lines)

(2) asynchronous serial ASYNC)

Use a Modem or Modem pool connection to connect a remote computer to the network through a public telephone network with a low communication rate.

(3) isdn bri (base group rate) Interface

This interface is used to connect an ISDN line to the Internet or other remote networks through a vro, enabling kb/s communication rate.

ISDN has two rate connection ports, one is the basic rate interface of isdn bri) and the other is the basic group Rate Interface (isdn pri)

The isdn bri interface adopts the RJ-45 standard, and the connection with the ISDN NT1 adopts the RJ-44-TO-RJ-45 Express Line.

Annotation method BRIx, such as BRI 1 and BRI 2.

Configuration Interface

(4) Console interface

Use the configuration special line to directly connect to the computer's serial port, and use terminal simulation software, such as a super terminal under windows) for local configuration of the router. The Console port on the router is mostly a RJ-45 port.

⑸ AUX Interface

The AUX interface is an asynchronous port and a RJ-11 telephone line interface type. It is mainly used for remote configuration, dial-up connection, and Modem connection. The AUX port and Console are usually provided at the same time because they are used differently.
